Full Throttle, Six Flags Magic Mountain

Location: Valencia, California

This year, self-proclaimed "Coaster Capital of the World" Magic Mountain tacks on another thriller to its already packed roster of 17. The newest addition is not only billed by the park as "the tallest, fastest looping roller coaster in the world," but it also features a zero-to-70 mph acceleration and a stomach-churning 160-foot loop through which riders will hurtle—twice. Welcome to the family, Full Throttle.
